I have a process in jBPM. The process has a Human Task. Also there are Data Objects: SrcData, CalcInter.

In the Human Task's Assignment Data I/O panel I need to read properties from the objects in Data Inputs section, and write a calculated variable in the property of CalcInter object in Data Outputs section (see picture).

Objects' properties reading in Data Inputs works as intended. As suggested here: How to call a getter method in the Data Assignments I/O in a jbpm task?

But writing Object property in Data Outputs in such way doesn't work. I've tried:

#{CalcInter.setAxx(axx)}
#{CalcInter.setAxx((int)axx)}
#{CalcInter.setAxx(#{axx})}

How to solve this? (And why is it so complicated?)

I've found that the issue can be solved by using MVEL notation instead of pure Java.

If in Data Outputs as a Target we use following expression:

#{CalcInter.axx}

The jBPM engine correctly updates the object property.

(How to use a Java style in the case and if it is possible — I still don't know.)
